[sane-devel] [Suggestion/Patch] xsane-preview: select scann area with given proportions
Peter Seiderer

Hello,
this is a suggestion for adding a new feature to xsane preview window.
I think it would be a nice feature to have the ability to determine a
given proportion of the selected scan area in the preview window,
e.g. 3:4, 4:3 for 1024x768 result pictures or 1:1 for quadratic results etc..
Attached a little patch with an first version for this feature.
Is there a possibility to set the cursor to a given position
in the window in gtk/gdk?
Any further suggestions/advices?
Peter
